In combat sport, specially in MMA, is a term used by a play-by-play announcer (e.g. Mike Goldberg). It refers to a ring strategy of a fighter who likes to throw consecutive rapid fire punches at an opponent to overwhelm them. This eventually leads to a knockout or a TKO because the opponent is unable to fight back due to the amount of punches being thrown at them.

1. Mike Goldberg: They call it punches in bunches by Chuck Liddell...

2. Most of Mike "Quick" Swick's knockout are due to usage of punches in bunches. Ben Saunders anyone?
